This article examines privacy as a generic process that occurs in all cultures but that also differs among cultures in terms of the behavioral mechanisms used to regulate desired levels of privacy. Ethnographic data are examined from a variety of cultures, particularly from societies with apparently maximum and minimum privacy, and from analyses of various social relationships, such as parents and children, in-laws, husbands and wives. It is concluded that privacy is a universal process that involves culturally unique regulatory mechanisms.This article addresses the question posed in the title, namely, is privacy regulation a culturally universal process or is it a culturally specific phenomenon? Like the rabbi of Jewish folklore faced with petitioners holding irreconcilable opinions, my answer is "yes, both positions are correct!" This seemingly paradoxical response is based on an analysis of privacy as (a) a culturally universal process involving dynamic, dialectic, and optimization features, and @) a culturally specific process in terms of mechanisms used to regulate social interaction. Thus, I view privacy to be culturally pervasive at one level of analysis and culturally unique at another level of analysis.The first section of the article summarizes a theoretical model and rationale for conceiving privacy as a cultural universal. Dilemmas, issues, and a strategy for dealing with the question of cultural universals are then discussed, followed by a review of ethnographic data related to privacy. ~ I wish to acknowledge my appreciation for comments on earlier versions of this article
